I would say it depends on were it is. If it is near a field it could be a staging area and I would say it's more than likely multiple deer. If it is in the middle of the woods and there isn't much other for cover it could be multiple deer. If it is in an area were there is plenty of cover then I would say take a guess, could be 1 could be 9. This is only my .02, that is usually the way I try to identify a staging area.
